I extended my machine frame and while assembling the gantry I noticed there is play in the rollers and the 2040 gantry. The gantry is 2040 extruded V slot and the nema 23 stepper motor is mounted to the same plate as the guide rollers. There are 2 guide rollers on top with the Motor drive and 2 guide rollers on the under side of the extruded. I looked in the parts store but could not find the plates I need. Might anyone be able to share a link to the Plates I need. TIA
